When I start the game there are certain objects in the game with different appearances than I remember them. For example the beginning gate has this weird blue square around the entrance swirl and for scientific analysis I checked out a gate on the farm and there wasn't a blue square. Can anyone help with this problem, because it's too difficult to play with problems like that.

EDIT: AARGH! All my other games have graphical glitches as well! I've looked up on Google for similar cases but there aren't any like my problem....
